It achieves a sleep sensation like weightlessness, and you won't feel pressure on your head or ears even when sleeping on your side. 【Unique Neck and Cervical Curve Shape】 Guides the neck to create the correct curve and supports the cervical spine. It fits firmly from the shoulders to the neck and does not put a burden on the head or neck. This is a new sensation pillow that will liberate you from being a pillow refugee. It supports the natural curve of the neck in any sleeping position without burdening the neck and shoulders. 【Comfortable Sleep in Any Position & Arm Support Area】 The sides of the pillow are designed to be slightly higher, supporting the ideal posture for back sleeping. It also reduces the burden on the shoulders and arms when sleeping on your side, reducing shoulder fatigue and stiffness upon waking. When sleeping on your side or stomach, there is a curve to place your arms, so you won't be unsure of where to put your arms. Because it is a memory foam pillow, you can sleep comfortably in any position: side, back, or stomach. 【Adjustable Height】 You can adjust the height by changing the orientation of the pillow. The low side is 8cm, and the high side is 12cm. People who like high pillows and people who like low pillows can use this pillow. In back sleeping, the head and neck are moderately supported, and in side sleeping, the natural curve of the neck and the natural position of the spine are supported. 【Excellent Pillow Cover with a Comfortable Feel - Clean and Comfortable】 The pillow cover uses a high-quality, soft-touch material and is treated with antibacterial and deodorizing properties to suppress the generation of odors.
